EMAIL SPOOFING: How to Prevent and Stop It


Most certainly, at least once in your life, you have been the victim of email spoofing. This is so because email spoofing affects everyone, whether they are high-profile corporations or ordinary people. You may learn everything you need to know about email spoofing in this post, including what it is, the causes of it, how to stop it, how to prevent it, and the tools used.

What is Email Spoofing?

Email spoofing is a technique used in spam and phishing attacks to deceive people into believing a message came from a source they either know or can trust. In spoofing attacks, the sender alters email headers so that client software shows the false sender address, which the majority of users believe at face value. Users will notice the counterfeit sender in a message unless they extensively examine the header. They are more likely to believe it if the name is one they are familiar with. Therefore, they will accept virus attachments, click harmful links, transfer sensitive data, and even wire company funds.

Due to the way, email networks are constructed, email spoofing is feasible. The client application assigns a sender address to outgoing messages; outgoing email servers have no way of knowing if the sender’s address is real or fake.

Spoofed messages can be found and filtered with the aid of recipient servers and antimalware software. Unfortunately, not all email providers use security measures. However, users can check the email headers included with each message to see if the sender’s address has been falsified.

Reasons for Email Spoofing

#1. Phishing

Phishing attacks are the typical result of email spoofing attempts. A phishing email may pretend to be from your bank, place of employment, or boss, or it may adopt other tactics to get information out of you, such as posing as a government agency. The hacker may use ransomware, steal existing account credentials, or gather enough data to create a new fake account.

#2. Identity coverup

A spoof email is private. Hackers occasionally use fake emails to hide their identities and gain the user’s trust by pretending to be from a respected company or person.

#3. Avoid spam filters

Hackers utilize fake emails to get around email spam filtering. When an email is faked, it is unlikely to be detected by spam filters and frequently appears to be a regular email.

#4. Identity theft

Numerous innocent people give personal information and login credentials to hackers when the counterfeit email looks reliable. For instance, hackers can demand identification confirmation or medical information.

How Does Email Spoofing Work?

A sender’s account is not hacked by email spoofing. It merely gives the impression that an email is coming from the sender. The difference is that if a sender’s account were genuinely hacked, the spoofer could access the sender’s contacts or use the account to distribute spam, harming the sender’s reputation in email. Deliverability is impacted by email reputation.

Simple Mail Transfer Protocol (SMTP) servers and email platforms like Outlook, Gmail, etc. are used in email spoofing attacks. The scammer modifies the FROM, REPLY-TO, and RETURN-PATH fields in the message header.

The development of email makes this possible. The TO, FROM, and BCC fields in the message headers are separated from the message body. SMTP lacks a mechanism for address authentication because security was not considered when it was developed.

How to Spot a Spoofed Email

You might be asking how you can quickly recognize a spoofed email now that you are aware of the various methods an email spoofer may use to pretend to be someone else. Keep an eye out for these red flags if you receive an email that makes you nervous.

#1. Suspicious email address

Make sure to verify that the email domain matches the legitimate domain of the sender, whoever they may be. Watch out for typos and similar-looking domains as well.

#2. The address doesn’t match the display name

If the display name and email address of the sender are different, this is another sign that the email is fake. Check to determine if the sender’s address on the current message matches the one used in earlier interactions and if it is someone you have spoken with before.

#3. The feeling of urgency

The sender may employ social engineering techniques to create a sense of urgency, pressuring you to respond or follow their instructions because faked emails are frequently used for phishing or other sorts of intrusions.

Even though not all spoofing emails will exhibit these characteristics, paying close attention to the sender’s address and display name might help you identify some spoofing emails that may have found their way into your inbox. Fortunately, the majority of well-known email providers have included extra security measures to assist in identifying fake emails, such as:

  • Sender Policy Framework (SPF): When sending an email, SPF verifies that the sender’s IP address is related to the email domain they are using.
  • DomainKeys Identified Mail (DKIM): To ensure that the email hasn’t been altered between the sender’s and recipient’s servers, DomainKeys Identified Mail (DKIM) is used.
  • DMARC, or Domain-based Message Authentication, Reporting, and Conformance: allows the sender to specify whether or not the receiver should be informed that the email is SPF- or DKIM-protected.

These security precautions can be used to confirm whether an email is authentic as well as to warn customers of spam and fake emails.

Real-World Email Spoofing Example

An IRS alert addressed one instance of an email spoofing campaign that was used to facilitate a second-stage wire fraud attempt. Employees in HR or payroll received fake emails that purported to be sent by executives in the targeted businesses during this assault. An urgent request for a list of all employees and their W-2 forms was made in the bogus emails.

This scam so far has been a typical email spoof. But there was a catch: after the initial phishing scam, another one appeared, asking the employee to send money via wire transfer. Business email compromise, or BEC, was used in this phase of the attack. This two-stage scam is still widely used in today’s society.

How to Stop Email Spoofing

Because the Simple Mail Transfer Protocol, which serves as the basis for sending emails, doesn’t require any authentication, it is impossible to stop email spoofing. That is the technology’s weakness. To combat email spoofing, numerous additional countermeasures have been created. The success rate, however, will entirely depend on whether or not your email service provider adopts them.

Most reliable email services perform further checks:

  • Sender Policy Framework (SPF)
  • DomainKeys Identified Mail (DKIM)
  • Domain-based Message Authentication
  • Reporting and Conformance (DMARC)
  • Secure/Multipurpose Internet Mail Extensions (S/MIME).

When utilized properly, these tools operate automatically and promptly reject fake messages as spam. Regular users can stop email spoofing by selecting a safe email provider and following solid cybersecurity practices:

  • Create temporary accounts when you register on websites. Your private email address won’t be included on dubious lists that are used to send fake email messages en masse.
  • Make sure your email password is strong and sufficiently complicated. Cybercriminals won’t be able to access your account and send false messages to your contacts as easily if you do this.
  • Examine the email headers, particularly if someone requests that you click on a link. Attackers with skill can create spoof emails that are exact replicas of real ones. Even if you have used them for a while, they can appear to be indistinguishable.

How to Prevent Email Spoofing

Malicious email messages still make it into users’ inboxes despite email security measures. There are various measures you may take to prevent falling victim to email spoofing, regardless of whether you’re an employee in charge of making financial decisions or someone who uses personal email while at work:

#1. Apply email security procedures.

Domain authentication is a technique used in email security protocols to lessen threats and spam. Sender Policy Framework (SPF), DomainKeys Identified Mail (DKIM), and Domain-based Message Authentication, Reporting, and Conformance (DMARC) are the email security protocols now in use.

SPF can only identify counterfeit sender addresses in the email’s envelope, which is used when an email bounces, during the delivery phase of an email. However, when used with DMARC authentication, SPF can identify a fake “visible sender,” a trick frequently employed in spam and phishing.

#2. Encrypt email

DKIM uses public and private keys to validate a sender’s identity. Each SMTP message must contain a set of keys that correspond to a public DNS record, which the receiving mail server verifies.

#3. Install a security gateway for email.

A group of technologies known as email security gateways, sometimes known as Secure Email Gateways, operate on a network level to filter emails that do not adhere to security policy guidelines. All incoming and outgoing email is scanned by an email security gateway, which may additionally have features for blocking viruses, spam, content filtering, and email archiving. Users are not at all impacted by these preventative measures because they take place at the network level.

#4. Utilize an anti-malware program.

Antivirus software may be able to detect and block them before spoofed emails reach their targets’ inboxes. Because attackers are aware of newly discovered vulnerabilities and move rapidly to exploit them, it’s critical to keep antimalware software up to date.

Is it illegal to spoof emails?

It is officially considered spoofing to create disposable email addresses, for example, to sign up for a free trial. But when spoofing intentionally attempts to impersonate another sender, particularly when the intention is to steal valuable data or money, the law gets involved.

How is email spoofing commonly used?

Simple Mail Transfer Protocol (SMTP) servers and email platforms like Outlook, Gmail, etc. are used in email spoofing attacks. The scammer modifies the FROM, REPLY-TO, and RETURN-PATH fields in the message header. The development of email makes this possible.
